Antirrhinum plant named ‘Amalia Pink’

ABSTRACT

A new and distinct cultivar of  Antirrhinum  plant named ‘Amalia Pink’, characterized by its upright and compact plant habit; freely branching habit; dense and bushy growth habit; dark green-colored leaves; freely flowering habit; and flowers that are dark pink in color.

Botanical designation: Antirrhinum majus.

Cultivar denomination: ‘Amalia Pink’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Antirrhinum plant, commercially known as a pot-type Snapdragon, botanically known as Antirrhinum majus, and hereinafter referred to by the cultivar name Amalia Pink.

The new Antirrhinum is a product of a planned breeding program conducted by the Inventor in Aalsmeer, The Netherlands. The objective of the breeding program is to create new freely flowering Antirrhinums with upright and compact plant habit, and attractive flower coloration.

The new Antirrhinum originated from a cross-pollination made by the Inventor in Aalsmeer, The Netherlands, of an unnamed proprietary selection of Antirrhinum majus, not patented, as the female, or seed parent, with an unnamed proprietary selection of Antirrhinum majus, not patented, as the male, or pollen parent. The new Antirrhinum was discovered and selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Aalsmeer, The Netherlands.

Asexual reproduction of the new cultivar by terminal vegetative cuttings since 2001, in Aalsmeer, The Netherlands has shown that the unique features of this new Antirrhinum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Amalia Pink have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity and daylength without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Amalia Pink’. These characteristics in combination distinguish ‘Amalia Pink’ as a new and distinct cultivar:

-   -   1. Upright and compact plant habit.     -   2. Freely branching habit; dense and bushy growth habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Flowers that are dark pink in color.

Plants of the new Antirrhinum can be compared to plants of the female parent selection. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Antirrhinum differed from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Antirrhinum had smaller leaves than plants         of the female parent selection.     -   2. Plants of the new Antirrhinum and the female parent selection         differed in flower color.

Plants of the new Antirrhinum can be compared to plants of the male parent selection. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Antirrhinum differed from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Antirrhinum were more freely branching than         plants of the male parent selection.     -   2. Plants of the new Antirrhinum and the male parent selection         differed in flower color and shape.

Plants of the new Antirrhinum can be compared to plants of the cultivar Balumhopi, disclosed in U.S. Plant Pat. No. 13,628. In side-by-side comparisons conducted in Aalsmeer, The Netherlands, plants of the new Antirrhinum differed from plants of the cultivar Balumhopi in the following characteristics:

-   -   1. Plants of the new Antirrhinum were more compact and more         upright than plants of the cultivar Balumhopi.     -   2. Plants of the new Antirrhinum had shorter internodes than         plants of the cultivar Balumhopi.     -   3. Plants of the new Antirrhinum had smaller leaves than plants         of the cultivar Balumhopi.     -   4. Plants of the new Antirrhinum and the cultivar Balumhopi         differed in flower color.

DETAILED BOTANICAL DESCRIPTION

Plants of the cultivar Amalia Pink have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photograph and following observations and measurements describe plants grown in Aalsmeer, The Netherlands, under commercial practice in a glass-covered greenhouse with day temperatures about 20° C., night temperatures about 12° C. and light levels about 10,000 lux. Plants used for the photographs and description were about three months from planting rooted cuttings in containers. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
